Winds outperformed the forecast yesterday and field observations noted substantial wind transport near and above treeline. While wind speeds are expected to drop significantly today fresh and sensitive wind slabs may exist in isolated areas in the forecast area. Exposed areas and leeward catchment zones near and above treeline deserve evaluation. This is particularly true on unsupported alpine slopes, the sidewalls of alpine couloirs, and in extreme terrain. Recent drifting and cornice growth and uneven snow surfaces are all clues that indicate nearby wind deposits. Do your own localized assessments and be suspect of terrain features that encourage drifting such as the leeward sides of ridgelines, gully features, and cross-loaded depressions.
